Cloud-native applications in Java are great, but… despite a fantastic ecosystem around Java, it falls short in containers, in comparison to Go or Node.js. The initial memory consumption, the startup time, and the optimizations for long-running processes are killer criteria in the cloud. Quarkus is a Kubernetes native Java stack tailored for GraalVM and OpenJDK. With Quarkus you can compile your application into a native executable, reduce the startup time to a few milliseconds, reduce the memory consumption to a few MB, and make applications ideally suited to run in containers. And with just a few lines of code Quarkus can invoke OpenAI to become a storyteller.
This workshop explores why it matters and how you can leverage Quarkus and GraalVM to build supersonic, subatomic, cloud-native applications.
In this workshop, you will learn how to:
  • Build Web applications with Quarkus
  • Use Hibernate and Hibernate with Panache
  • Build event-driven microservices with Apache Kafka
  • Monitor your applications
  • Prompt OpenAI with Semantic Kernel APIs
This is a hands-on experience, so please bring your own laptop with the following installed and configured on your laptop prior to the start:
  • Java 17
  • A working container runtime environment (Docker, Podman, Rancher Desktop, etc)
  • GraalVM 22.3, Java 17 version
  1. Linux -
  2. Windows -
  3. MacOS -
  • An OpenAI account
